Diabetes mellitus Type 1 is a chronic disease that rates 2/1000 adolescents that may have their daily life changed. In order to describe and analyse how these adolescents organize their daily activities and how they face the fact of having a chronic disease, 15 teenagers who lived in Vitoria, ES, and used to enroll in public health programs for diabetic were interviewed. They also answered the MAC, which stands for "Daily Activities Map". Two hundred twenty four students from public schools, who weren't diabetic bearers, filled this form. Quantitative analyses of MAC and content analyse of interviews were done. Results of the forms showed that adolescents, in general, do more activities aiming themselves, and they've done it at home, like watching TV. Diabetic adolescents reported that they have some problems like going to doctor's appointment and miss the school classes, but they don't consider having their daily life modified. Results also pointed that there is no expressive differences between the two groups.
